Decoding SKF 3310 A-2RS1/C3MT33
- 33Series
- Double row angular contact ball bearings, 33 series. Series differ in outside diameter and width even when the bore is the same.
- 10Bore
- Bore 50 mm (10 × 5).
- A-2RS1/C3MT33Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
3310 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 3310 A-2RS1/C3MT33 measures 50 mm across the bore and 110 mm across the outside diameter; its width is 44.4 mm (50 x 110 x 44.4 mm).

SKF 33 series bearings are double row angular contact ball bearings. They handle radial and axial loads in both directions and are built for applications that call for rigidity and precision. We supply this series with rubber seals and C3 internal clearance for demanding conditions.
The part number tells you what you are getting. Take 3310 A-2RS1/C3MT33: 3310 is the basic number and defines the size and series. The A suffix denotes an optimized internal design. 2RS1 means a rubber seal on each side, keeping grease in and contaminants out. C3 sets radial internal clearance above standard, and MT33 identifies the factory grease. Other sizes in the series include 3309 and 3311.
These bearings suit equipment with combined loads and moderate speeds: centrifugal pumps, compressors, industrial fans, machine tools, transmission units, agricultural machinery and conveyors. Because they are double row and angular contact, they take axial forces in both directions, which a single row deep groove bearing does not do as effectively.
Selection depends on the radial and axial loads, the rotation speed and the environment. Choose C3 clearance when temperature differences between shaft and housing are expected, or when assembly tolerances call for it. The 2RS1 seals handle dust and moisture; in very dirty areas or where water sprays, consider extra protection. MT33 grease covers a wide temperature range, though severe duty may require periodic relubrication.
When replacing a bearing, confirm that dimensions and clearance match the original. Cross-brand equivalents exist but are not always direct: the same basic number can carry different suffixes and performance. Checking with a specialist before substituting one brand for another is a practical step.

Frequently asked questions
- SKF 3310 A-2RS1/C3MT33 bearing: what are its dimensions?
- SKF 3310 A-2RS1/C3MT33 measures 50 mm across the bore and 110 mm across the outside diameter; its width is 44.4 mm (50 x 110 x 44.4 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 3310.
- What does the C3 suffix mean on these bearings?
- C3 indicates internal radial clearance greater than standard. It is used when temperature gradients exist between shaft and housing, or when more tolerance is needed for assembly. It does not change load capacity but must be factored into the design.
- Are the 2RS1 seals replaceable?
- No, the 2RS1 seals are an integral part of the bearing and are not designed to be replaced. If damaged, replace the complete bearing. For applications requiring inspection or relubrication, versions with metal shields (ZZ) or without seals are available.
- Can I use these bearings at high speeds?
- Yes, but rubber seals generate somewhat more friction than metal shields, which can limit maximum speed. For high speeds, consult the manufacturer's tables or contact us to evaluate a suitable alternative.
